+---------------
Beg pardon, but the only restriction I've found is that ( can not be used as
a single-character name; it is possible to define a macro called ".F", for
instance, and call it as "..F". I've not found a need to define "." as a
macro, but it could be useful e.g. to monitor memory usage as you define
macros, since troff will not only stop defining at .., it will execute the
macro called "." if it exists; make "." do a ".pm" for a quick memory-usage
debug check. (Or ".rn pm .".)
